To all whom/it may concern: Y 1

Be it known that we, RoBERT B. HUGUNIN, MARY L. HUGUNIN, and WILBER A. LANE, at present residing at N orthHavel'nin the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Kneading-Rollers and Retiring Han dles therefor.

.Ourinvention relates to improvements in kneading-rollers and retiring. handles 6111i ployed with the 'samo, the objects of the improvements being,first,to enable the construction of several fluted rollers together'at one time direct from the raw material; second, to enable the constructionof several fluted ro1lers at one time, with flutes varying indepths and side angles,bymeans of whichthe material being workedis alternately compressed and. stretched; third, the application to doughworking rollers of retirable handles and handle-catches forsecuring the same and an expanding spring at the inner end'of the handle-body to move the same outwardly within reach of the hand when the confining catch is released. We attain these objects by means illustrated in accompanying drawings, in which v p Figure 1 is a plan view of a roller embodying our invention. Fig. 2 is a longitudinal view of same, showing our handles retired. Fig.

3 is an end view of roller having our improvements. Fig.4 is a cross-section. of the same and of material from which we preferably.

form the roller. Fig. 5 is a cross-sectional view of half of a roller, the other half being shown;

in dotted lines; Fig. 6, sectional plan of our retiring handle; Figs. 7 and'S, views showing. application of handle-fastening catches to ends of roller; Fig. 9, view of a disconnected handle-catch and screw; Figs. 10 and 11,

modification in construction of ourroller;

Figs. 12 and 13, modifications in construction of retiring handles 'for rollers. Fig. 14. is a view of retiring handle, modification shown in Fig. 13, the spring beingomitted; Fig. 15,

washer and screw for securing handle, modification shown in Fig. 13; Figs. 16- and 17,

cross-sections of fluted rollers, showing modification of features of our fluted roller.

Similar letters refer to similar parts in all the figures. r

A is a cross-section of material from which we form our fluted roller, round, fluted, and solid, several lengths at a time, by single cuttings from each of the planes b c d e, inclose ing the material, as shown in Fig. 4, and a cross-section of material from which our roller is formed in halves, several lengthsat a'time, by a single cutting from each of the planesfg, as shown in Fig. 5, subsequently cut to lengths of roller andsecured together.

A is across-section of material from which a modified form of roller possessing features of our invention is cut round and fluted, several lengths at a time, by two cuttings from planes b d, as shownin Fig. 16, also a cross- .section of a modified roller possessing fea-' tures of our invention, out both round and fluted, several lengths of rollers at a time, by four cuttings from planes b 0 die, as shown in Fig. 17.

B is the body of our fluted roller embraced within planes a a a a, from which as a-base our improved flutes, are constructed. (See- Fig.3.) For a modified construction of some see Fig."l0.

. B is a modification of roller-body embraced within planes at a a a and .flutesprojected from same, as shown in Fig. 16.; Also a modified form in construction of our. flutes is shown in Fig. 17.

side angles, as'show'n in Fig. 3, and thereby greater smoothness in working, and by means of which the material is alternately compressed and stretched as under pressure in bread-kneading. The flutes are shown projected from planes a a. a a at right anglesto A modifiedconstruction of our roller in secplanes h h, passing quarterly through the roller-center, as shown in Fig. 3, the nearest to a right-angle side of the flute being, preferably, the corner side of the same, as shown in Fig. 3.

The construction of the retiring handle is shown in Fig. 6, in which E is the handlebody, F the handle-pin secured to same, having movable handle G secured loosely to pin F by means of knob M and the springJ acting from the inner end of the handle-body, as shown in Fig. 2.

Figs. 12 and 13 are modifications of retiring handles, showing handle-body E, pin F, handle G, spring J, and washer H, and screw 1' for securing the handle in moving position on pin F. The washer and screw are shown in Fig. 15 in. detail.

Fig. 14 shows an end of roller 13, rolleropening D, and body of retiring handle E, with the spring (shown in Fig. 13) omitted.

Fig. 9 illustrates the securing-catch K and screw 1 detached from end of roller; D, opening at ends of roller corresponding with and for the admission of retiring-handle body E. F is the handle-securing pin, connected with body E; G, movable handle secured loosely to pin F by knob M, as shown in Fig. 6, or by washer H and screw 1, (shown in modification, Figs. 12 and 13;) J, compressible coiled spring employed at inner end of handle-body E in retiring-handle opening D; K, catches for securing retiring handles; L, holes in handle-bodies E for tongues of catches K, by means of which the handles are secured when drawn out, shown in Figs. 1 and 7, and when retired, as shown in Figs. 2 and 8. On releasing the catches the spring .1 forces the handle outwardly within reach of the hand for adjusting and securing in working position. By retiring the handles when not in use the space occupied by the roller is lessened by the lengths of the retiring handles, adding to compactness and convenience of roller.

The retiring handles are equally adapted to the plain rolling-pin and to which we apply them. The fluted roller is also adapted to the plain rolling-pin handles and to which we apply them when desired. Our kneadingroller is also adapted for employment with power and can be made of any required di ameter and number of flutes projected and out; both round and fluted, several lengths at a time from planes inclosing the material from which formed, requiring one cutting from each plane, including flutes located on same.

We are aware that radiating fluted rollers, the product of two operations, turning and fluting, with considerable difi'iculty in graduating have been made, and we do not broadly claim such; but

What we do claim, and desire to secure by Letters Patent, is-

1. The kneading-roller herein described, constructed with uniformly-shaped flutes,one side of the flute being nearly at right angles with, and the other at a less angle with the base of the same, in application alternately reversed, providing thereby, alternate and uniformly-varying depths, with uniform side angles between the said flutes, substantially as shown, and for the purposes specified.

2. The kneading-roller herein described, constructed in sections, one section a square, the other of flutes constructively united in pairs, and applied to sides of said square, substantially as shown, and for purposes specified.

3. The combination with a roller of the retiring handles herein described, constructed arranged and applied substantially as shown and for the purposes specified.

4. The combination with a kneading-roller of the retiring handles herein described, each constructed and working independently of the other, each having a handle-body, and handle-pin to which the handle is movably attached, a fastening-catch adapted both to secure the body of handle within roller, and when drawn out for use and a compressible coiled spring all applied and working substantially as shown, and for purposes specified.
